Abstract
The utility model relates to a mechanical measure instrument for a street section, which is used for checking and detecting the outline dimension of an underground street section. The utility model is mainly composed of a scale A and a measuring scale B. The utility model is characterized in that the measuring scale B is connected to the scale A via a scale support C. The utility model has the advantage of simple structure; only two persons can implement the measurement of the street section in any shape.
Description
The utility model belongs to the mechanical type drift section measuring tool of checking and measuring the defeated wide size of underground passage section.
Present measurement to the mine working cross dimensions, except that the electronic measuring instrument measurement is adopted in the minority mine of external a few countries, overwhelming majority of countries all adopts tape to carry out, the personnel selection of this method is many, speed slowly, low precision, and electronic measuring instrument complex structure, cost height, maintenance difficult.
The purpose of this utility model be to design a kind of simple in structure, cost is low, in light weight, safe and reliable, be easy to carry and easy to operate mechanical type drift section measures instrument.
The utility model mainly is made up of scale A, gage B, it is characterized in that gage B is connected on the scale A by slip rod support C.
The advantage of this utility model be simple in structure, cost is low; In light weight, volume is little, is easy to carry; That mechanical type does not need is explosion-proof, the down-hole is safe and reliable, only need two people just can carry out the measurement of Any shape drift section.
Description of drawings: figure one is the structural representation of this utility model; Figure two, figure three are applicating example synoptic diagram.
A-scale among the figure; The B-gage; C-slip rod support.1-gage chi cap; 2-gage shrinkage-rule; The 3-trip bolt; 4-gage base chi; The 5-mircrometer gauge; The 6-indicating piece; 7-gage chi handle; The 8-trip bolt; The circular clamp nut of 9-; The 10-rubber washer; The 11-packing ring; 12-scale base chi chi cap; The 13-packing ring; The 14-rubber washer; The 15-clamp nut; The 16-slide block; 17-air-bubble level cover; 18-measures dish; 19-scale base chi; The 20-trip bolt; 21-scale shrinkage-rule; 22-scale shrinkage-rule cap; The 23-air-bubble level.
Now in conjunction with the accompanying drawings this utility model is described further: scale A is used for supporting gage B and gage B is slided along scale A.Scale A is by chi cap (12), (22); Base chi (19); Shrinkage-rule (21); Trip bolt compositions such as (20).The spreading of base chi (19) and shrinkage-rule (21) is all used thread connection, and its length connects a joint or a more piece according to the drift section size, is marked with the mm scale at scale A.Gage B connects with scale A by slip rod support C, is used to measure drift section.Gage B is by chi cap (1); Shrinkage-rule (2); Trip bolt (3), (8); Base chi (4); Mircrometer gauge (5); Indicating piece (6); Chi handle compositions such as (7).Shrinkage-rule (2) is socket with basic chi (4), is slidingly matched, fixes with trip bolt (3), and basic chi (4) and mircrometer gauge (5), mircrometer gauge (5) is thread connection with chi handle (7), and indicating piece (6) is welded on the chi handle (7).Be carved with the mm scale on the gage B, mircrometer gauge (5) precision 1/10mm.Gage B can revolve three-sixth turn around the rod support axle by sliding seat C.Slip rod support C is used for supporting gage B, and gage B is slided along scale A.Slip rod support C is by slide block (16); Trip bolt (15); Measure dish (18); Circular clamp nut (9); Compositions such as packing ring (10), (11), (13), (14).Wherein measure dish (18) and spend for being carved with 360, and the disk of air-bubble level (17) is housed, it is mainly used in the relative positions on the measurement instrument such as determining the gradeline spring line, and is used to carry out the polar coordinates measurement.
Measure the instrument relation of being linked and packed:
One: assembling scale A, equipped slide block (16)
1. load onto basic chi (19), shrinkage-rule (21) chi cap (12), (22) respectively.
2. length is distinguished spreading base chi (19), shrinkage-rule (21) on demand.
3. go up cover top shoe (16) at basic chi (19), and temporary fixed with trip bolt (15).
4. shrinkage-rule (21) is inserted basic chi (19), temporary fixed with fastening screw (20).
Two: assembling gage B
1. on chi handle (7), load onto mircrometer gauge (5).
2. on mircrometer gauge (5), load onto basic chi (4).
3. the shrinkage-rule (2) that will install chi cap (1) inserts in the basic chi (4), and fixes when interim with trip bolt (3).
Three: general assembly
On slip rod support C, load onto earlier and measure dish (18), rubber washer (14), packing ring (13), gage B trip bolt (8) is also done temporary fixedly, adorns rubber washer (10), packing ring (11) then, the circular clamp nut (9) of screwing on, arrive this, drift section measures instrument and always sets complete.
Using method is given an example:
The tunnel is the measurement of section, adopts artificial common measuring in conjunction with the polar coordinates method of measuring to measure, and scale A can be vertically or horizontal positioned when measuring.Now vertically to be placed as example: as figure two, figure three.
At first, scale (A) vertically is put in midline position, and rod support is fixed on the stringcourse level, measure center line to two with gage (B) and help, on the stringcourse to top board, down to the rail level distance.Find out position in the tunnel according to center line, (A) moves in the tunnel with scale, and arched tunnel such as figure two then move to rod support skewback line place in this way, measure full section each several part size.Trapezoidal cross-section such as figure three in this way, when section hour, can directly adopt common measurement method to measure, when section is bigger, can adopt the polar coordinates method to measure when directly measuring inconvenience, with measurement, with contrast one by one by each good spot size of designing and calculating on ground in advance, its difference is the error of design and construction, with the national standard contrast, determines whether the tunnel is qualified.
Claims (3)
1, a kind of mechanical type drift section measurement instrument that is used to check measurement underground passage profiled outline size is characterized in that: insert basic chi (19) also with the temporary fixed fixed ruler A that forms of screw (20) by shrinkage-rule (21); By shrinkage-rule (2) insert basic chi (4) and temporary fixed with screw (3), more basic chi (4) one ends and chi handle (7) are pegged graft, with the fixing composition of mircrometer gauge (5) gage B; On the basic chi (19) of scale A, put slip rod support C then, and chi handle (7) one ends of gage B are enclosed within on the axle of rod support C, make it, load onto rubber cushion (10) packing ring (11) hold-down nut (9) of screwing on around 360 ° of rotations of axle.
